Renewable Energy and Power (REAP) announced expanding marketing activity for the company’s Power Stac vanadium redox flow battery (VRFB) power storage system.
California has mandated that, as of 2020, all new houses and multi-family residences of three stories or fewer, along with all major renovations, must be built with solar panels. With other states to follow, the demand for power storage for solar generation is certain to grow.
The ability of vanadium redox flow batteries to fully cycle and stay at 0% state of charge makes them ideal for solar storage applications where the battery must start each day empty and fill up depending upon the load and weather.
Power Stac can last for 10,000 cycles with no significant degradation, equivalent to 25 years of storage, matching the life of solar panels and wind turbines.
Unlike lead acid and lithium batteries, Power Stac energy storage systems do not go into thermal runaway in warm climates. Power Stac Energy storage is non-explosive and non-flammable, and can be remotely monitored and requires minimal maintenance.
Power Stac has a low levelized cost of storage a calculation of the cost of energy stored over a battery’s life, taking into account all operating and maintenance costs, together with efficiency. In addition to the cost benefits, the working environment and productivity are helped by the improved storage abilities of Power Stac.
“The added value and sophistication of our cost saving energy storage system makes it a natural for residential and commercial solar power generation,” said REAP CEO Donald MacIntyre. “The quickly expanding commercial grower’s market is just one of the areas where Power Stac will prove to be an ideal solution to the need to store the generated power.”
